14 years without a splash! You must be a very careful
worker! You have two choices:
something mildly acidic (e.g. 5% acetic acid) or, if it's
on white fabric, bleach. Toluidine blue has little affinity
for cotton, and would probably come out with a few washes
anyway. You're lucky it's not alcian blue, which is very
permanent.
